摘要:
针对某高铅贫锌多金属矿石铅品位5.50 %、锌品位0.37 %，方铅矿与闪锌矿、黄铁矿、黄铜矿等金属硫化物关系密切，铅、锌分离难度大等特点，进行了重选—重选尾矿快速浮选—浮选尾矿铅、锌分离试验研究。结果表明：在最佳条件下，浮选闭路试验获得了较好指标，实现了铅?⑿康挠行Х掷耄笾星ψ芑厥章?6.11 %，银总回收率92.36 %；锌精矿锌品位52.45 %，锌回收率82.41 %；各产品含杂均达到了标准要求，经济效益显著。

Abstract:
The lead and zinc grades of a polymetallic ore with high lead and low zinc content are 5.50 % and 0.37 % respectively.Galena,sphalerite,pyrite and chalcopyrite are closely related to metallic sulfide.It is difficult to separate lead and zinc.In light of these features,experimental research has been carried out on gravity separation-rapid flotation of gravity tailings-lead and zinc separation in flotation tailings.The results show that under optimal conditions,closed flotation circuit has obtained good index and effective separation of lead and zinc;in silver lead concentrates,overall lead recovery rate is 96.11 % and silver recovery rate is 92.36 %;in zinc concentrates,zinc grade is 52.45%,zinc recovery rate is 82.41 %;impurity content in each product meets the standards and the economic profits are significant.
